HP has issued an update to remove a keylogging mechanism found in audio drivers included with some of its high-end laptops. The Conexant HD Audio Driver Package preinstalled on 28 HP laptop models came with a file called MicTray64.exe that logged all the user’s keystrokes to a local file. The log file was never sent to HP, but its mere presence on users’ computers was an issue, as malware or any other person could copy the file and extract passwords from that file.
